While the shapes have here been illustrated and described as structural channels, it is obvious that the invention does not reside in the use of this particular structural shape but rather in the provision of outwardly flaring flanges on the side edges of the shapes so that, when such shapes are arranged side by side, the edges of the flanges will contact to provide expansion spaces for permitting the web portion of each structural element to expand and contract transversely without distortion or movement of the facing as a whole.

It is to be understood that the words "shapes", "structural shapes", channels and structural channels as used in the description and the appended claims, refer to the articles of manufacture commonly known by engineers, architects and mechanics by these terms and commonly used in the production of structures of different kinds.
